Package Exports

postcss-apply

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (postcss-apply) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

postcss-apply

PostCSS plugin enabling custom properties sets references

Disclaimer:
Just toying around an interesting idea, not even a spec.
The plugin is in a very early state, some features are missing.

Installation

npm install postcss-apply --save-dev

Usage

var fs = require('fs');
var postcss = require('postcss');
var apply = require('postcss-apply');

var input = fs.readFileSync('input.css', 'utf8');

postcss()
  .use(apply)
  .process(input)
  .then(function (result) {
    fs.writeFileSync('output.css', result.css);
  });

Examples

input:

:root {
  --toolbar-theme: {
    background-color: rebeccapurple;
    color: white;
    border: 1px solid green;
  };
  --toolbar-title-theme: {
    color: green;
  };
}

.toolbar {
  @apply --toolbar-theme;
}
.toolbar__title {
  @apply --toolbar-title-theme;
}

output:

.toolbar {
  background-color: rebeccapurple;
  color: white;
  border: 1px solid green;
}
.toolbar__title {
  color: green;
}
